A portable super-audio frequency induction heating device and method

Abstract

The invention discloses a portable ultrasonic-frequency induction heating device and method. The portable ultrasonic-frequency induction heating device comprises a power supply, an on-off control circuit and a driving circuit, wherein the on-off control circuit comprises a transistor Q11, a transistor Q8, a transistor Q5 and a thyristor Q9, and the driving circuit comprises a chip U1, a transistor Q7, a transistor Q4, a transistor Q6, a transistor Q3, a transistor Q2, a transistor Q1, a diode D5, a diode D6, a diode D8, a diode D7 and a transformer T1. According to the portable ultrasonic-frequency induction heating device, the circuit is simple, the number of electronic elements is small, switching on and switching off can be achieved rapidly, stability and reliability are guaranteed, a cooling device is light, the utilization rate of a magnetic core of the transformer T1 is high, during push-pull work, only one of the transistor Q1 and the transistor Q2 which are symmetrical is switched on each time, and switching-on loss is small. When the portable ultrasonic-frequency induction heating device works, a strong magnetic bundle with the polarity changing suddenly is generated inside an inductor L2, electromagnetic induction of the strong magnetic bundle acts on a heated metal part, eddy current is generated, joule heat can be generated due to the fact that resistance exists inside the heated metal part, and electric energy is converted into heat energy.

Description

Technical field [0001] The invention relates to a heating device, in particular to a portable super-audio induction heating device and method. Background technique [0002] At present, super-audio induction heating technology is rapidly being promoted in the energy industry due to its high efficiency, cleanliness, and environmental protection. It conforms to the environmental protection and sustainable development policy, and is one of the green and environmentally friendly heating processes. Traditional super audio frequency induction heating devices are mainly used in industrial production processes, and have defects such as high manufacturing costs and difficult equipment maintenance. [0003] At present, most of the domestically produced super-audio induction heating devices are installed in fixed locations due to their large size. They can only be heated at a limited position and angle, and cannot be used in automobile maintenance, railway maintenance, construction and constr...
